Thanks guys! That's exactly how I rinse my car, but it's been over 100 here in Oklahoma lately. I'll try dual action polisher with a white foam pad next. I'll go get that glass polish and try that as well. What speed would probably be good for most situations. A 3 or 4?
Both actually. Washed my black 02 Grand Prix GTP the other night in the shade and tried drying afterwards but left water spots in the paint and glass. I tried using Mg cleaner wax with a buffer on the paint to try to take them out, but that didn't work.
